HD Quality Video

Thanks to significant advances in video technology, HD quality video has become the industry standard for video and television broadcast resolution. Developments in equipment, including the ultra-big screen televisions that are available today, have made it necessary for the signals to become more refined and better received.

HD quality video refers to the high definition parameters that are currently in place for the signal. Three particular measurements are used to explain HD quality video: frame size (measured in pixels, usually 1280x720 or 1920x1080), scanning system (an "i" refers to interlaced scanning, a "p" refers to progressive scanning) , and frame rate (number of frames per second). Combining these parameters results in HD quality video descriptions that look something like, "1280x720p50," this description indicates that the frame size is 1280x720 pixels, with progressive scanning at a frame rate of 50 frames per second.

While all of these measurements may seem overwhelming and rather complicated, there are really only a few different combinations that you will find once you start shopping for HD quality video equipment. All of today’s television sets will automatically be equipped to handle HD quality video signals; there will be only a slight variation across different manufacturers and models.
